| Abstract: |
| Objective To study the manufacturing process of porous surface coating of sintered porous tube, and the heat transfer properties of copper sintered porous layer surface were measured. Methods Copper powder was sintered on the outside layer of brass using sintering mold, and the heat flux and enhanced heat transfer coefficient of the porous sintered tube were calculated through experiments. Results The obtained results showed that the enhanced heat transfer effect of the brass after sintering copper reached about 10 times as high as that of the light pipe in alcohol. Conclusion The smaller the particle size of sintered copper powder, the greater the heat flux of sintered tube and the better the heat transfer performance. |
